That is some good info there. I found the top end of the MB500 a bit much... super sizzly and harsh. If the MBFusion can stay equally clean, but with a touch more organic character to the top end, that will be a very nice unit for many! I assume they have fixed the noise issue also, since the MB500's I tried were very, very hissy (I assume due to that super goosed top end).

Nice.

Go figure, I must have got the good one.:hyper::D My MB2-500 is quite as a church mouse. And truthfully, the top end with my MV5 sounds superb.

I also have one neo 112 8 ohm. So if i run both cabinets i will have 500 watts right? The 112 is only 300w. Will i blow it up then?

A 4x10 will likely be much louder than a 1x12. You'd be better off trying the 4x10 by itself, and if you need more volume, getting a matching 4x10 cab would be worth considering.

The 1x12 is still useful for quiet gigs & rehearsals and for use as a monitor in conjunction with PA support.

You won't. The 410 will take most of the amp's energy. The 112 won't be as loud, and it won't take the whole amount of the 500 watts. Each cab will take what it can give, but the amp will "see" a 4 ohm load and give the full 500 watts, even if it's not evenly distributed.

I spent some time comparing my MB Fusion to my MB500 the other day, and one of the things I was specifically looking for was how much clean headroom I could get out of each. I have to say, I was somewhat surprised to find that I was able to get the MB Fusion to get just as "loud and clean" as the MB500, if not a tad bit more clear. The added harmonic content with the MB Fusion adds some nice "air" and "life" to the high end, and if you don't drive the input too hard, you can definitely keep it out of anything approaching and obvious overdrive, but still push the amp pretty hard. I had expected that I would have to deal with a certain amount of preamp overdrive to get full volume, but I really didn't. Now, if you want it, it's certainly there, but it's nice to know that you can stay clean, clear, and tight and still get all the volume you'd want.

A bit more, perhaps. I did notice that with the MB Fusion, as you push it into a more gritty/growly tone, it also get a bit meatier, warmer, and slightly less distinct. The MB500 also lets you dial in some grit/growl, but it will stay a bit more "distinct" and not as warm/round as the Fusion. You can definitely get plenty of headroom/volume out of the MB Fusion, and you do not have to drive it into overdrive to get all of its volume. But I must say that it almost has a dual personality, depending upon whether you keep it clean or push it hard. I do think that this is pretty darned cool, and due in part to the fact that Bob Gallien is actually using all of those tubes. :cool: But for some folks, they might not want any of this "dual personality thing," and for these folks, the MB500 is the way to go.

Oh, and it may be worth mentioning that the MB Fusion is about an inch deeper than the MB500.

IME, preamp tubes don't run all that hot, and I've never seen a dedicated preamp tube fan, that i recall; even in preamps with 6 or more.
the fusion does have what appears to be sufficient vents over the tubes to expedite that.
